To all whom it may concern:

Be it known that I, FRANK TEMPLEMAN, a citizen of the United States ofAmerica, and a resident of Chicago, county of Cook, and State otillinois, have invented certain new and useful Improvements in l`ountain Brushes, of which the following a specilieation.

The main objects of this invention are to provide an improved fountainbrush; to pro- `vide a brush of this nature with means for directingiiuid streams from the sides of the brush toward its center, to theremeet in the axial center line of the brush and produce a fountaincausing the water to spread outwardly from the center' of the brush tothe contact ends of the bristles; to provide a fountain brush withimproved clamping means for securing the brush to the holder; and toprovide a fountain brush with an iinproved arrangement of jet orificeswhereby the brush is kept in thoroughly cleaned oondition while inoperation.

An illustrative embodiment of this invenf tion is shown in theaccompanying drawings,

in which- Figure l is a perspective View of a fountain brush constructedaccording to this inn vention.

Fig. 2 is a vertical longitudinal section of the brush.

Fig. 3 is a plan view of the brush stock and part of the brush holder,

Fig. 4 is a perspective view of a spo-nge and its support which may besecured in the brush holder as a substitute for the brush.

This invention provides a construction of fountain brush which isparticularly suitable for cleaning automobile bodies. lt is usuallynecessary to employ a sponge for this work since brushes ordinarilyconstructed, cause the grit and dirt which is being removed to scratchthe finish of the automobile. Fountain brushes have been constructed todirect a stream of water slightly in advance of the brush and some havebeen arranged to direct streams of water into the brush and also fromthe center out, but they have all been arranged in such manner that theultimate result is impracticable for the class of work which is the aimof the present brush to accomplish. Prior devices frequently required aspecial construction of brush since the water was directed through itsback, and others were not thoroughly self-cleaning since the jets ofwater were directed at the sides of a brush having the bristle tufts soarranged as to prevent the water from reaching the center of the brushand keeping it thoroughly saturated with a flow of liquid from thecenter outwardly.

In the present construction, the tufts of bristles are arrangedL in rowsradiating from the centerI of the brush, thus providing a plurality ofopen spaces through which the streams of water may be directed so as toproduce a fountain at the center of the brush. ln this manner, the waterflows outwardly toward the operating or contact ends of the bristles,permitting the brush to be used with equal success when in invertedposition. In the fountain brushes of this class which may now beobtained on the market, the water fails to thoroughly moisten the entireoperating surface of the brush when used in inverted position, most ofthe water flowingover the outer edge of the brush stock, andbeingentirely useless, with the resultthat the grit, etc., scratches thesurface being cleaned. For this reason no brushes have been providedwhich are suc cessful for cleaning automobile bodies, and this work isgenerally accomplished by means of a sponge. Y

The present invention provides a very substantial brush with a castholder provided with a cored out water conduit surrounding itsperiphery, thus permitting the brush to withstand severe use without thewater conduit becoming bent, and the present invention also provides abrush which, because of the peculiar manner of ow of water through thebrush, may be successfully employed for extremely heavy work withoutinjury to the surface operated upon.

Referring to the drawings, the brush support l consists of a castingforming a back 2 having a central opening or slot 3 for receiving a camor clamping device l mounted on the stock 5 of the brush. The cam il isrotatably mounted and is adapted to readily slip through the slot 3 whenturned longitudinally therewith. lt may then be turned transversely tothe slot, the shoulders thereof riding upon and engaging the back 2, asshown in Fig. 2. The casting l at one end has extending from one end athreaded socket 6 for receiving a brush handle 7 comprising a pluralityof pipe sections coupled together to form an extensible handle to whicha hose coupling may be secured. The

. duit and is provided with a plurality of jet orifices 9, the orificesat opposite sides of the conduit being arranged to direct streams ofwater radially toward the center of theV brush and to meet iii-pairsalong a line passing through the center of the brush transversely to theplane of the back thereof. A few of the jet orices are arranged todirect water against the tufts of bristles at the outer edge 10 of thebody of bristles in order that the matter to be removed from the surfacebeing cleaned is moistened in advance of the brush. orifices meeting ona center line passing through the brush, a fountain is rthere createdwhich causes the water to flow outwardly to the operating ends of thebristles,

even when the brush is used in anv inverted position on the under sideof a car body.

.F or the purpose of causing the operating surface of the brush toconform more closely to the form of the fountain produced in theLcenter/of the brush, the brush stock 5 is made of decidedly convexcurvature. Also for the purpose of not obstructing the flow of watertoward the center of the brush, the tufts of bristles 11 are arranged inrowsl between the jet orifices in the holder, which rows radiate fromthe center of the brush outwardly, as shown in Fig. 3.

A special cast back 12 is provided for supporting a. sponge 13 which maybe stitched to the back with chamois 14, as shown in Fig. l, The spongemay therefore be readily substituted for the brush when it is desii-edto use the device in light work where a sponge may bey preferred.Inmanufacturing thebrush holder, the core for the conduit is supportedthrough the member 6 and apertures 15. These apertures are finallyclosed by screws, as shown'in Fig. 1, and provide means by which theconduit may be `ushed out if necessary.

A rubber buffer 16 is provided surrounding the rimrof holder l toprevent injury to surfaces losing'` cleaned by contact with said holder.

In the operation of the device, the water Copies of this patent may beobtained for B i the arrangement of `et Y :a .p Y the present inventionprovides a highly elnwhich enters `the brush holder from the handle 7flows in two streams to the right .and left around the cored out conduitat the periphery of the holder. The jet orifices beingy suitablyproportioned with this conduit cause the water to How in a plurality ofstreams of substantially equal strength between the rows of bristles andmeet in pairs of streams in the axial line of the brush center,producing a fountain which causes the water to flow outwardly to theoperating surface of thebrush, regardless of the position in which thebrush is heldV during its motion over the surface being cleaned.

It may be seenfroni the foregoing that cient fountain brush particularlyuseful where the brush is employed in rather heavy work.

` 'Although but'one specific embodiment of this invention has beenherein shown and described, itwill be understood that some of thedetails of the construction shown may be altered or omitted withoutdeparting from Y the spirit of this invention as defined by the .lessremoved from the brush holder.

2. A fountain brush comprising a brush and brush holder, said brushbeing provided Vwith radial rows of bristle tufts, and said holder beingprovided with a conduit encircling the brushV and having opposed jetorifices arranged to direct streams between the rows of tufts atdifferent angles so as to meet at points indifferent planes more or lessremoved from the brush holder.
